ARTIFICIAL BUI LDING-STONE.

.srEGIFICATION forming part of Letters Patent No. 698,727, dated April29, 1902.

Serial No. 71,952. (No model.)

Be it known that I, J A0013 0. MoCLENAHAN, a citizen of the UnitedStates,residing at Coldwater, in the county of Branch and State ofMichigan, have invented new and useful Improvements in ArtificialBuilding-Stones, of which the following is a specification.

My invention relates to improvements in artificial building-stones; andthe objecl-isto provide a building-stone made from artificialcomposition of materials which shall meet and supply all the purposesfor which a build ing-stone is required in the erection of buildings,walls, partitions, and similar structures and construction. j

Another object is to provide a stone for the general purposes indicatedwhich is corn posed of segregated component parts or eleinents adaptedto be set and secured together to form a single integral stone.

A further object is to provide a hollow buildingstone composed ofseparate elements, parts, or pieces adapted to be packed in the smallestpossible space for transportation.

"With these objects in view my invention consists in a building-stonepossessing novel construction of parts and their operative aggroupmentin combination.

I have fully and clearly illustrated in the accompanying drawings apreferred form of the constructions of my improved buildingstone, andreference being thereto had Figure 1 is a View in elevation showing theinner face of a molded slab or plate constituting one of the sidepiecesof the stone. Fig. 2 is a longitudinal'section taken on the line 22 of Fig. 1. Fig. 3 is a top plan view of a stone, showing the parts asunited and secured together. Fig. 4 is a perspective View of one of theinterlocking partitions. Fig. 5 is a detail horizontal section of thejoint of the side piece and the partition,showing the cement binderinserted in the coinci dent grooves.

A designates a plate or slab made of suitable indurated cementitioussubstances or ingredients, and of such size, shape, and configuration asmay fit it to the uses intended. I have indicated it as being an oblongrightangle body having a plain outer face and an tially as shown.

inner face made to suit the purpose of connection to its counterpart.This plateAconstitutes one of the duplicate side pieces of the stonewhen placedinposition. Atdetermined locking partitions may be insertedin the ways and be lodged on the wall of the closed ends. The inner wallof the plate may be strengthened by suitable ribs 5, arranged substan-The arrangement of diagonal ribs between the inner walls of the Verticalribs and inclined and outwardly-directed ribs united at the middle ofthe outer vertical ribs and terminating at the corners of the stonegives ample strength and is preferred. In the inner faces of thevertical ribs are formed vertical grooves 6, which are intended to alinewith coincident grooves in the ends of the interlocking partitions andform therewith the means provided'for locking the partitions and theside plates together. Because of the strengthening-ribs the body of thestone plate may be made lighter and thinner than when omitted, and thusa substantial saving of material is accomplished without sacrifice ofrequired strength.

B designates the interlocking partitions,

consisting of such blocks or plates of made or artificial stone as maybe suitable. They are of such width as shall determine the width orthickness of the stone and of such height as to approximately reach frombottom to top of the vertical ways in the side pieces of the stone. Inthe opposite sides of the interlocking partitions adjacent to the endsare formed vertical grooves 7, in alinement with the grooves 63, the twoforming ways or wells into which properly-prepared cement 9 is poured orplaced, so that when the ends of the partitions are arranged in the waysbetween the ribs and the cement inserted in the grooves and indurationeffected the parts of the stone are held firmly bound together.

The interlocking partitions B are formed with openings 8,which aredesignedfor ventilationand to serve as handholds in handling them andwhen inserting them in position in relation to the side plates of theassembled parts.

To assemble the parts, the side plates of the stone may be arrangedparallel with each other and the vertical ways directly opposite toeachother. The ends of the interlocking partitions are then slipped in thevertical Ways and pushed down into position, and then the cement isplaced in the grooves between the walls of the vertical ways and theinterlocking ends of the partitions and permitted to harden, when theparts are rigidly fixed together.

What I claim is 1. An artificial building-stone comprisingoppositely-arranged side pieces formed with vertical ways or grooves,and grooves in the walls of the ways. partitions having their endsformed to fit in the ways or grooves and having vertical groovescoincident with those of in the walls of said ways, and a cement binderin the registering grooves of the partitions and ways.

In testimony whereof I affix my signature in presence of two witnesses.
